Carpet Beetles

Carpet beetles are a common household pest that can cause damage to fabrics, fur, feathers, or virtually anything made of organic fibers. Adult carpet beetles do not cause damage to fabrics, as they feed outdoors on pollen or not at all. Instead, it is the larva or immature stage of these insects that cause damage.


Carpet beetles are small, oval-shaped insects that range in size from 1/16 to 1/8 inch long. They can vary in color from black, brown, or white to a combination of these colors. The larvae of carpet beetles are elongated and hairy, with a tapered shape at both ends and grow up to ¼ inch long.

Carpet Beetle Lifecycle

The lifecycle of carpet beetles begins when an adult female lays her eggs. Carpet beetles can lay their eggs indoors, although they may also infest the nests of birds, mice, and other insects. After mating near sources of light, females can lay more than 100 eggs at a time, which will hatch into larvae within seven to 35 days. The larvae will then feed on the surrounding materials, including carpets, furniture, and clothing. The larvae go through several molts before they pupate and emerge as adults.

Habits Of Carpet Beetles

Carpet beetles are attracted to light and are often found around windows. Adult females lay eggs on lint around baseboards, carpet edges, cracks, in ducts, on mouse carcasses, or in similar situations.

Carpet beetles prefer to feed on natural materials, such as wool, silk, fur, feathers, and leather. They may also feed on synthetic materials contaminated with food or body oils.

Damage Caused By Carpet Beetles

The larvae of carpet beetles chew through fabrics, leaving behind irregular holes or damaged areas. They can also cause damage to natural history collections, including bird nests, taxidermy, and insect collections.

In severe cases, carpet beetle infestations can cause significant damage to carpets, furniture, and clothing.

Prevention and Control of Carpet Beetles

Preventing a carpet beetle infestation can save time and money in the long run. Prevention and control requires a combination of sanitation, exclusion, and insecticide treatments.
